Moving to Lima in July

Hey everyone - my husband and I are selling off everything and moving to Lima in July. We are moving for his job and have a place to stay for the first few days. While he's working, I'm going to be on my own, learning the lay of the land, finding a place to live, learning the language, basically flying by the seat of my pants.

Do any of you have any rock star suggestions on how to not lose my mind while I'm out getting lost by myself? Any thoughts on how to get to know the neighborhoods, locals, find a job, make some friends, find an affordable place to live?

My husband will be working in Jesus Maria - so we are looking to live in Miraflores, Jesus Maria, Magdalena del Mar, or San Isidro.

Thanks!
